Marinising a Toyota Hilux 1KD-FTV Common Rail Diesel

[Hotpoker]

I am looking to build a 6.5m aluminium hard top fishing boat (planning hull), and I like the idea of an inboard diese for economy, but frightened by the capital cost!

A local wreckers specialises in 4x4 and he has a number of late model 1KD-FTV diesel Toyota Hiluxs, a couple with less than 10,000km on the clock! I can get a low km engine (and supporting bits) for around NZD$9000.

There is a local outfit that sells heat exchangers (NZD$1700) and marine intercoolers ($900NZD) that would suit the engine:
http://www.heatexchangers.co.nz/
And they may also be able assist with the water cooled manifold (waiting confirmation).

So from what I can figure I will also need:
1.) Plumbing;
2.) Raw water pump;
3.) Bell housing;
4.) Engine mounts;
5.) Customize the wiring harness.

The Toyota 1KD-FTV appears to be the same engine as the Nanni Z4:

And there seems to be some reasonable support info like this users manual which includes a nice wiring diagram!

My questions are:
1.) How do i work out what raw water pump to use and how to fit it?
2.) Is it finacially going to be worth while? I want to avoid second hand as these are generally less efficient;
3.) How much of a nightmare are the electrics going to be?
4.) Is it worth the hassel!?

My intention is to do it as a 6 month project.

Thanks!

Been thinking about the same idea with a KZ engine (mech injected version).

Raw water pump is probably driven off an extra belt on the front of the engine (maybe a new pulley needed. Simple construction to build a mount that bolts to the front of the engine. Size wise just see what similar HP marine engines are running (the Nanni etc) and get one from Jabsco or similar.

$9k starting point for the automotive engine is probably too high to make the job worth doing. You can get a fully marinized low hours/rebuilt KZ engine @185hp for $11,500, whereas your marinized KD is probably heading for $15k+ by the time you get the heat exchanger, intercooler, turbo, raw water pump, cooled manifold, exhaust elbow etc all done, plus you then need to get it all working properly. I love the common rail electronic diesels, but your savings over a production marine engine start to get slimmer once you are up over $15k with leg adapters, leg, and all the other bits still to work out. If you can do a lot yourself you will still save some money, but once you factor in the reduced resale value it starts to even up.
I don't think that the electrics would be a huge hassle unless they auto engines are taking feedback from gearbox sensors or other parts of the car. If the sensors are all on the engine it shouldn't be too scary.
One technical question about those engines is do they run an oil cooler standard as an auto engine? If not, I would be considering fitting one for marine applications where you are constantly producing high hp. Not a major to fit, but again a few extra $'s.

hmmm i would start with a more commonplace and less expensive engine... if its a planning hull id keep the engines light, ie a pair of vw 1.9 diesels ?

or perhaps a single GM 6.5 l v8.. they are both relatively inexpensive engines.. im not sure what is commonplace arround your neck of teh woods but start with a search in the local paper or junk yard for prices on good diesel engines....

just remember that 15000 will but alot of gas.. so a used mercruicer and a replacement short block could be the cheap and safe alternative

Thanks for the replies. I have actually found a low km 1KD for $6.5K ....which may make things more viable?

I prefer the 1KD over the 1KZ (although a good engine too - i have one in my Surf), as the common rail improves fuel efficiency by about 15%, and also has higher torque and KW / hp. Not sure about the oil cooler - howwever they do have fuel cooler.

I have considered a VW or PSA (citroen/peugot) 1.9 diesel - however in NZ parts for the euro cars are generally more expensive - as is the servicing. As jap cars are more common here, and therefore the parts are cheaper and more readily available.

A GM or similar is not an option - their weight and size is not practical for the size of boat i am looking at. I am keen for the engine to be in the 250-300kg range.

This topic comes up every few months, and there is litterly a ton of information about marinizing a diesel engine. As a caviat I have never tried it, but the process is not in any way cheap or as easy as it seems on the surface. Fundamentally the demands of a vehicle and marine engine are different, and there are a lot of places to screw up even with the best of intentions.

Just from the begining remember that car engines are not normally designed for the type of constant load over long periods of time that Marine engines see, which is why most marine engines started off as industrial or aggricultural equipment.

That being said if you are sold on it check out

Where can I get the fully marinized, rebuilt KZ engine? Can you please provide contact details. An email address or website would be fine.

Thanks

You will also need a different flywheel, maybe the harmonic balancer and the gears. The injection pump will probably have to be reprogrammed too.

To Aliboy,

Thanks for the info.
